The Nokia Lumia 920 has the fastest and most advanced screen of any smartphone right now. This is due to the use of Nokia PureMotion HD+ technology but what is it and how does it work? Here we take a look at the things you need to know about PureMotion HD+ on the Nokia Lumia 920.

The first thing you need to know about Nokia PureMotion HD+ on the Nokia Lumia 920 is that it’s over twice as fast as the displays of its nearest competitors. This means you’ll find far less blurring when scrolling or navigating, sharper rendering when watching video or playing games and the best overall image quality on screen possible.

Jussi Ropo, Nokia’s Senior Technology Manager has revealed in an interview over at Nokia Conversations that “All rendering should happen at a stable 60fps as only then you get rid of the jaggedness in the moving content. You can say it’s a prerequisite for all the further improvements.” That’s why you’ll find the Nokia Lumia 920 running at such a fast frame rate, to reduce the amount of blurring.

The next stage is to make sure the liquid crystal in the LCD screen can change from one colour to another in the fastest time. Ropo reveals that when you’re running a screen at 60fps you need to be able to change colours every 16.7ms in order to produce a blur free image.

The Nokia Lumia 920 has been designed to run, on average, at 9ms, or as Ropo puts it, “On average it takes about 9ms for all of the transitions so regardless of e.g. what shade of blue you are turning into what shade of yellow, it is always below 9ms. This is the biggest step forward in the screen speed of the Lumia 920.” By comparison, other competitor phones will have a like-for-like transition speed of around 23ms.

How has Nokia done this? By boosting the voltage to each LCD pixel when required, effectively overdriving performance on the panel

It’s a great insight into a technology that needs to be seen to be believed and certainly puts the Nokia Lumia 920 ahead of the competition, whether that’s a rival Windows Phone device, or an Android or iOS smartphone.
